Abstract

A magnetic element having an excellent direct-current saturation characteristic by effectively utilizing a size of a core is provided. The magnetic element has cores (11, 7, 8 and 17) formed of a magnetic material, buried conductor parts (21, 31 and 41) in the magnetic material, and a plurality of branch conductor parts (22, 23, 34, 35, 36, 37, 42 and 43) branching from the buried conductor parts (21, 31 and 41) to be a plurality of parts and separately turning around the magnetic material.
